Hellloooooo what is wrong with this guy?? well maybe what is wrong with your friend. Did I hear you saying that both ( I mean BOTH) are paying the apartment? well so it means she owns it too. Well so why can he bring his dog and be in peace and why she has to be scared if they piss the silly rugs.

Girl if they havent move together yet, and they have this kind of disagreement, what do you think will happen when they live together.

I have rugs too and actually I hate rugs, but for winter I am force to use them, well my cat is ripping them apart, and do I care? noo. Do I care she is destroying my sofas, the things is material things are replaceble, living creatures not.

Is very sad to give them away, or to leave them in a cage, it will be a punishment.

I am sure she is in a difficult situation because she is in love with him, but love is a matter of sharing, and when you share you get equal amounts
Ask herself if he will get rid of the dog if they make poo on them...
Well those were my 3 cents
